WIRE-CUTTING DEVICE.

Specification of Letters Patent. Patented 0013. 27, 1914:. Application filed April 6, 1914. Serial No. 829,745.

clamped by means of nuts 12 bearing against the outer faces of the side walls 1 0.

One edge of the lever 6 is provided with a To all whom it may concern: i I Be it known that I, JOI-INIT. OIIE, a citizen of the United States, residing at Kansas City, in the county of Jackson and I I I plate 16, which is secured to the lever by lrneans of a bolt 18. The side or cutting l edges of the plate 16 converge in the direction of the lower or pivoted end of the lever,

and are adapted to cooperate with the inner,

similarly converging cutting edges of a pair of plates 20, which are shown as secured by bolts 22 in suitable recesses 24 in the side walls 10 at each side of the recess .4. The

upper faces of the plates 20 thus lie flush with the upper surfaces of the side walls 10,

thereby forming a suitable support for the legs of the staple 26 which is to be operated upon.

In this working position, as illustrated by the dotted lines in Figs. I and III,the staple is retained by means of a. pair of plates 28, sup )orted upon the top faces of the side walls 10 and secured thereto by bolts 30 near one end of each plate and by bolts 32 near the other end thereof, the latter bolts serving also to secure a tie-plate 34- which securely braces the parts and also limits the lowering movement of the lever 6, which is provided with a notch 36 to afford the proper amount of clearance for said tieplate. The inner edges of the retaining plates 28 are provided with notches 38 adjacent the cutting edges of the plates 20, for accommodating the staple legs and positioning them for the shearing action of the eutting elements 16 and 20. For this purpose the forward sides of said notches 38 act as gages or stops for the ends of the staple legs, and the other sides of said notches serve as abutments for the sides of the staple legs and are so outlined as to position said legs with their axes running slightly obliquely with reference to the cutting edges of the plates 20. Furthermore, these abutting sides of the notches 3S diverge in a forward direction sulliciently to permit spreading of the sheared portions of the staple a distance apart slightly greater than the distance between the remaining portions of the staple legs (see Fi IV).

An addiitlonal retaining means for the State of Missouri, have invented a new and useful lVire-Cutting Device, of which the following is a specification.

The object of this invention is to devise a means for providing points on wire, and, in particular, upon staples, and in carrying out this object as regards the pointing of staples, the means devised is adapted to impart a slight spreading action to the ends of the staple simultaneously with the pointing thereof.

The means illustrated in the present embodiment thereof consists in. a shearing mechanism having provision for spreading the staple legs simultaneously with the l shearing action, together with means for properly positioning the staple in relation to the cutting elements. With this general object in view, the invention will now be described with reference to the accompanying drawing showing one form of the same as embodied in practice, after whichthose particular features and combinations which are deemed to be novel will be severally specitied in the appended claims.

In the drawing-Figure I is a plan view ofthe device; Fig. II is a longitudinal sec tion on the line II--II of Fig. 1; Fig. III is a transverse section on the line IIIIII of Fig. 1; and Fig. IV represents plan views of a staple before and after the pointing operation, respectively.

Referring to said drawing, a bed plate 2 is shown having a recess 4 in its upper face, within which is mounted a lever 6a This lever is pivoted at its lower end upon the bolts 8, which are adjustably mounted in the side walls 10 of the recess 4:. The inner ends of the bolts 8 are reduced (see Fig. III) for fitting in suitable recesses of the lever atits pivotal point, the shoulders of said reduced portions abutting .against the adjacent side faces of the lever. This enables the lever to be adjusted in order to center the same pro erly in said recess 4 for a pur ose hereina ter referred recess 14 for accommodating a wirecutting.

which is adjustably mounted in a slide-way at the rear of the bed plate 2; and a bolt 4:6, which is carried in the side walls of the slide-way and adapted to engage any one of a series of bolt openings are in the slide 42, serves to secure the latter in adjusted position according to the length of'staple being operated upon.

By means of the above-described construction and arrangement, it will be apparent that a staple (or single strands of wire, if preferred) positioned in the manner illustrated in Fig. 1, will, upon swinging of the lever to effect cooperative shearing action of the members 16 and 20, be pointed as illustrated in Fig. IV; and furthermore, that the pointed portions will be spread slightly farther apart for a purpose found useful in certain arts. Difierent lengths of staples may be so treated according to the adjustment of the slide member 42, and the cutting member 16 may be maintained always in correct central relation with reference to the plates 20, by proper adjustment of the pivot bolts 8.

WVhile the foregoing represents what is now conceived to be the preferred form of embodiment of the invention, the right is reserved to all such formal departures therefrom as may be fairly embraced within the scope of the appended claims.

Claims:

1. In a device for cutting and bending wire, the combination of a wire-shearing means, and means for holding and positioning the wire including a positioning member having an edge for positioning the wire at the rear of the portion to be sheared and an edge at an angle to said first edge and adapted to permit slight lateral deflection of the sheared portion of the wire.

2. In a device for cutting and bending wire, the combination of a wire-shearing means, and means for holding and positioning the wire including a positioning member provided with a notch in the path of the shearing means, one side of said notch forming a stop for the end of the wire, and the other side of said notch extending at an angle permitting slight lateral deflection of the sheared portion of the wire.

3. A device for pointing staples, comprising a stationary cutting means having a pair of non-parallel cutting edges, means for positioning a staple with its legs overlying said cutting edges, and a movable cutting member having a pair of cutting edges adapted to cooperate respectively with said non-parallel edges to shear the ends of said staple legs.

4. In a wire-cutting device, the combination of a pivoted cutting member having a pair of cutting edges converging in the direction of the axis of said member, and a stationary cuttingmeans having a pair of nonparallel cutting edges located in the path of said movable cutting edges andadapted to cooperate therewith.

5.

9. A device for pointing staples, comprising a stationary cutting means having a pair of non-parallel cutting edges, a pivoted lever, a cutting member carried by'said lever and adapted, upon movement of the lever, to be brought between said edges and into cooperation therewith to shear the staple legs, means for positioning a staple with its legs overlying said stationary cutting edges, opposite sides of said lever at its pivotal point and permitting adjustment of the lever to center said movable cutting member with relation to the stationary cutting means.
